head to head
Nioh 2 asks more than Code Vein, and the gap is execution.

Execution · Practiced Mastery
Anime soulslike pairing pattern-learning boss fights with flexible class builds.

Execution · Practiced Mastery
A stance-switching action RPG where input precision meets deep loot theorycraft.
Code Vein leans Execution (Practiced Mastery); Nioh 2 leans Execution (Practiced Mastery).
Nioh 2 leans clearly harder on execution.
Code Vein
Dodge timing and stamina management in melee
Nioh 2
Stance switching, ki pulse, burst counters demand inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Code Vein
Bosses are scripted patterns, never adaptive
Nioh 2
Scripted enemies, no adaptation
Nioh 2 leans a little harder on variance, though the gap is small.
Code Vein
Fixed enemy placement; minor drop randomness
Nioh 2
Loot drops with affix randomness
Nioh 2 leans a little harder on optimization, though the gap is small.
Code Vein
Blood codes and gift builds reward theorycraft
Nioh 2
Deep build crafting and stance theorycraft central
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
